...Soviet satellite launched in 1957. U.S. scientists learned they could track the satellite's orbit by listening to changes in its radio frequency, relying on the same principle that explains why the pitch of a car's horn seem to change as the car speeds by. The Navy's TRANSIT navigation system was developed in the 1960s, relying on six satellites and designed originally for use by submarines. More than 10 satellites were eventually launched, though ground units had to wait up to several hours to pick up a signal. Meanwhile, engineers Ivan Getting and Bradford Parkinson began leading...
...host of other problems aggravated Panama's electorate, chief among them security, education and an antiquated public-transit system. "I have voted for the PRD for the past 25 years, but this time I [tried] my luck with Martinelli," says Pedro Gomez, owner of a small Panama City cobbler shop who says he was finally tired of "receiving nothing in return. At least Martinelli promised to give scholarships and free books to children, and my sons need them."

That includes Vice President Joseph Biden, who said Thursday morning on the Today show that the swine flu virus could spread easily on airplanes, and that he has advised his family against traveling anywhere on mass transit. "When one person sneezes, it goes all the way through the aircraft," Biden told Today host Matt Lauer. "I would not be, at this point, if they had another way of transportation, suggesting they ride the subway." (See the top 5 swine...
...fact, as Dr. Richard Besser, the acting director of the Centers for Disease Control and Prevention (CDC), pointed out just a few hours later, there's no real risk for a healthy person in the U.S. to ride mass transit - not with the outbreak as small as it is currently. It's true that crowded trains and subway cars can be a vector for disease transmission if sick people are on board. You can catch the flu if you're within about six feet of a sick person - otherwise known as the "breathing space" - who coughs or sneezes...
